the annoyance ceases, and is presently full-blown again. 
It is fond of floating at the surface of its prison, the base 
dilated at the top of the water, like a swimming Nudi- 
branch, the body hanging downwards, with the tentacles 
widely expanded. 
It cannot be considered a common species ; but where it 
does occur, it is usually in some numbers. It is easily 
obtained when discovered, as it does not inhabit holes or 
crevices, but adheres to the smooth rock ; it does not 
appear to indue its body with gravel, or any extraneous 
substances. Mr. Holdsworth found it not uncommon at 
Guernsey, with the imexpected habit of lodging under 
stones on the beach, at low water. At Dartmouth the 
same observer records its occurrence on the roots of 
Laminaria, as well as on the rocks. 
In my original notice of the species, I have mentioned 
the readiness and profusion with which the acontia or 
armed filaments are shot forth from the body on the 
slightest provocation. Subsequent observation has abun- 
dantly confirmed this irritable habit. The character and 
armature of the cnidm are also there noted. 
The localities of the species are as yet but few, though 
they are widely scattered.
